Jason Giambi reacts after striking out against the San Francisco Giants on Sunday.

All signs are pointing to Jason Giambi’s second season with the Rockies being finished with a week remaining in the season.

Giambi strained his left biceps tendon while swinging in the Rockies’ final at-bat in Sunday’s 4-2 loss to the Giants. He’s scheduled for an MRI, but Rockies manager Jim Tracy said he’s pretty certain that Giambi won’t play again in 2010.

“I dont like his chance of seeng any more action,” said Rockies manager Jim Tracy. “He’s sore today, really sore, and the prospects of him getting an opportunity to take another at-bat between now and Sunday, I wouldn’t think they’re very good.”

Giambi is hitting .244 with six home runs and 35 RBIs in 176 at-bats. He’s tied for the team lead with Seth Smith with two pinch-hit homers.

Other injury news: Smith returned to the team after a nasty bout with the flu, one that required I.V. treatments. Ian Stewart, meanwhile, is not at the ballpark after being struck with the same flu bug.

Then there’s Miguel Olivo. It isn’t every day that a catcher is out of the lineup because he was kicked in the head on the field by his own shortstop. It happened Sunday on a bizarre play in the ninth inning in which Troy Tulowitzki and Olivo both sprinted toward a popup after Giambi and Jonathan Herrera lost it in the sun.

Tulowitzki caught the ball between the mound and first base. As Olivo flashed past him, he stumbled and was inadvertently kicked in the head by Tulowitzki. Olivo would have caught Ubaldo Jimenez tonight in Jimenez’s final start of the season at Coors Field, during which he’ll go for his 20th win, but he’s out with what Tracy described as whiplash symptoms.

“He had pretty nice little egg on his head after being kicked,” said Tracy. “That position is dangerous enough in itself. And if you’ve got a knot on your head, you’re not taking the chances of seeing how many foul tips a guy can take off the mask.”
